Turning over Investigation of Low-Speed Guideway Switch for High-Speed Maglev Transportation

Abstract

In this paper, investigations on turning over of the first low-speed guideway switch for high-speed maglev transportation are introduced. Through geometric nonlinear analyses and comparisons for several characteristics during the turning over process of the switch, a schema with minimum position deviation, smooth changes of line types, gentle variations of stresses, and driving forces, is obtained. Based on the test and verification, the correctness of the theoretical analyses and the feasibility of the turning over schema are proven. The turning over schema has been applied to the low-speed guideway switch and obtained satisfied results. INTRODUCTIONThe low-speed guideway switch for high-speed maglev transportation is the main equipment for maglev trains to transfer from one track to another (Wu, 2003). Just as the high-speed guideway switch (Zhu, 2011), it is also composed of a beam, a set of mechanical subsystem, and the electronic control subsystem.
